[j-nsp] Layer 2 loop prevention - ACX5048

[Aaron Gould]

My Juniper account SE helped me solve it with active-interface...works nice.

(spared you the other portion of the config, let me know if you want to see
it)
set routing-instances 20015 protocols vpls multi-homing peer-active
set routing-instances 20015 protocols vpls multi-homing site site1
identifier 1
set routing-instances 20015 protocols vpls multi-homing site site1
active-interface primary ge-0/0/32.15

LDP VPLS - RFC 4762 - FEC 129 this works for multi-homing ce and preventing
Layer 2 loops using "active-interface primary"
